ADJUSTABLE FIXTURE FOR WINDOW-SHADES.

SPECIFICATION forming part of Letters Patent No. 790,946, dated May 30,1905.

Application filed December 9, 1904. Serial No. 236,223.

To all whom, it ntay concern:

Be it known that we, FRED SNVILLIAMs and WARD C. SILLIMAN, citizens ofthe United States, residing at Rome, in the county of Oneida and Stateof New York, have invented a new and useful Adjustable Fixture forWindow-Shades; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The invention relates to an adjustable fixture for window-shades, andhas for its object to improve the construction of window-shade fixturesand to provide an exceedingly simple device of great strength anddurability capable of being readily manufactured at a very low cost.

A further object of the invention is to provide a window-shade fixtureadapted to be quickly applied to a window and capable of readyadjustment to accommodate windowshades having spring rollers ofdifferent lengths.

Another object of the invention is to dispense with spring-actuated andvarious other forms of pivoted locking devices which are liable to getout of use and to provide simple means for enabling an adjustablebracket to be firmly locked in its adjustment by the weight of thewindow-shade, whereby the bracket will be effectually prevented frombecoming accidentally released when in use.

With these and other objects in view the invention consists in theconstruction and novel arrangement of parts hereinafter described andshown, and particularly pointed out in the appended claims.

In the drawings forming part of this specification, and in which likenumerals of reference designate corresponding parts, Figure 1 is anelevation of a portion of a window provided with adjustable window-shadefixtures constructed in accordance with this invention. Fig. 2 is avertical sectional view of the same. Fig. 3 is a detail perspective viewof one of the brackets. Fig. 4: is a detail perspective view showing thefront of the casing. Fig. 5 is a similar view showing the rear face ofthe casing.

Referring to the drawings, 1 1 designate adjustable brackets designed tobe located at opposite sides of a window, as illustrated in Fig. l ofthe drawings, and adapted to receive the journals of an ordinaryshade-roller. Each of the brackets is constructed of a single piece ofrod metal and is arranged within a casing Q, constructed of sheet metalor other suitable material. The bracket consists of a ratchet-bar and anapproximately L-shaped arm 3, extending outward from the outer end ofthe ratchet-bar and consisting of a depending substantially verticalportion and a projecting horizontal portion, which terminates in a head4:, having an opening to receive the journal of the shade roller. Theopening of one of the heads is round, and the other head is providedwith a polygonal slot for the reception of the journal which isconnected with the spring of the shade-roller. The depending verticalportions of the L- shaped arms of the brackets offset the shaderollerfrom the casings and enable the shaderoller, with its window-shade, tofit more snugly to the window frame or casing. The ratchet-bar, which isarranged within atransversely-disposed horizontal groove 5 of thecasing, is provided at its top with a longitudinal series ofsubstantially segmental projections or teeth 6, formed by stampingsegmental recesses or indentations in the front or outer face of theratchet-bar, and these projections or teeth,which are thrown forward bythe downward movement of the arm of the bracket, are adapted tointerlock with corresponding indentations 7 of the inner face of thecasing. The indentations 7 are formed at the top of the groove of thecasing, and in order to render the latter reversible to enable it to beused at either side of the window it is also provided at its bottom withsimilar indentations 8. The indentations 7 and 8 at the top and bottomof the groove or bend of the casing are arranged at intervals and thoseat the bottom are located opposite the spaces between the indentationsat the top of the casing, the said indentations being alternatelyarranged, as clearly shown in Figs. 4: and 5 of the drawings. When itisdesired to move the ratchet-bar longitudinally for adjusting thebracket, the outwardly-extending arm is swung upward, thereby partiallyrotating the ratchet-bar and carrying the projections or teeth rearwardout of the indentations. This permitsthe ratchet-bar to slide freely,and as soon as the arm is released it will drop back I and carry theprojections or teeth automatically into engagement with the indentationsof the casing.

The casing is provided with perforations for the reception of suitablefastening devices for the purpose of securing it to the window frame orcasing, and the inner end of the ratchet-bar is bent at an angle to forma stop 9 for limiting the outward movement of the ratchet-bar from beingwholly withdrawn from the casing.

What we claim is 1. A device of the class described comprising a casingprovided on its interior with indentations, and an adjustable brackethaving a horizontally-disposed ratchet-bar slidable in the casing, andprovided at intervals with projections or teeth fitting in theindentations whereby the ratchet-bar is interlocked with teeth into andout of engagement with the indentations, substantially as described.

2. A device of the class described, comprising a sheet-metal casing,having a groove or bend and provided on its interior with indentationsstamped in the metal, and a bracket having a ratchet-bar slidable in thecasing, and provided with projections or teeth stamped from the metal ofthe bracket and fitting in the indentations, substantially as described.

3. A device of the class described comprising a reversible casingprovided on its interior with upper and lower spaced indenta tions, anda bracket having a ratchet-bar arranged Within the casing, saidratchet-bar being provided with projections or teeth for engaging theindentations of the casing, substantially as described.

In testimony whereof we have hereto affixed our signatures in thepresence of two witnesses.
